The new write as JSON APIs should be visible to all Clipboard/DataObject API callers (existing or new API).

• In or out of process
• With copy = true or not
• Legacy platforms with type access to System.Text.Json and BinaryFormatter

• Need full tests documenting legacy MemoryStream behavior to ensure the following points are sensible
• Asking for <MemoryStream> in new typed APIs should always give back the raw stream for HGLOBAL
• Asking for <SerializationRecord> should NRBF decode HGLOBAL data
